Just reading with interest the descriptions of the Linear Power supplies - but the description for PS10K80, PS18K71E, PS18K71S and PS15K63 appears truncated on my Firefox browser so I can't read it.. is it possible to update these descriptions?

Although the info PDF for the v3 TA3020 modules mentions the PS10K63 should I presume this has been replaced by the PS15K63?

sorry for bombarding your forum with questions, just had a wave of enthusiasm :D

I was wondering if you could tell me what the possible benefits of your PS design would be compared to that stock PS which just has the 4700uf caps and a KB10005 10A Bridge rectifier. It would be much appreciated.

thanks!

the power supply use fast rectifier diodes, rated at 16 or 25A depending on the model, or shottky diodes for the power supply modules which have the output voltage below +-50V. the current capability of the board is larger, so is the total capacity of the capacitors from the board. the total energy stored by them is up to 270 Joules depending on the board. (the 6x18mF board has this total energy).
the amplifier will perform better especially at the low frequencies and can reproduce a more natural sound since the voltage rail will sag less when the amplifier will deliver maximum power.

Thanks. I'm not familiar w/ the brand of caps you use for the PS. I thought I read somewhere you chose them for their very low ESR. Is this accurate?

Are those snubber caps on the 6x10000uf/50v psu?

Here is the schematic of the power supply. most of the components values are same, except the diodes and the capacitors are different from a board to another.

Hello Cristi,
could you post the size of the linear supplies (length-width-heigh)? I am interested by 4x18000uF/71V+2x18000uF/71V.
thanks.
